Klassifikationens roll på www: en studie av webbmiljöns påverkan på klassifikationens principer och funktioner
Principles that guide how a classification system should be structured have existed for more than a century. Traditional classification principles can be of great value for the design of classification schemes directories on the web. However, there are differences between the library context in which these principles originated, and the web. This thesis aims at investigating how changes in the context of classification affect the application of traditional principles of classification on the web. Another purpose is to see what implications this has for the design of classification schemes on the web.

Fosforgödslingseffektivitet i långliggande bördighetsförsök
Rapid population growth and the fact that phosphorous is a limited resource implies that the question regarding an efficient use of phosphorus is of great importance, and consequently,that the phosphorous use efficiency should be as high as possible. The view on phosphorous use efficiency, and how this is calculated, has varied over time. This has had great implications on what type of research that has been conducted, which have resulted in an
inconsistency between the academic?s view on the subject and recommendations received by farmers. The purpose of this paper is to calculate the phosphorus use efficiency in the Swedish long term fertility experiments.

#VisitOurCountry : Nationella turistorganisationers användning av sociala medier
Purpose: The purpose of this essay is to describe the social media usage of five European official national tourism organizations (NTO). The essay proceeds to discuss and evaluate the findings, whilst reflecting on the advantages of social media usage from the point of view of an official national tourism organization.Method: The authors used three different methods of research: one structured observation to study the national tourism organizations? everyday work in social media, one field stimulation to study if and how different NTO respond if a prospective visitor makes them a direct question via social media and finally an email interview to gain insight into NTO?s underlying strategies and policies about social media usage.Theoretical framework: The theories that have been used in this paper include the Uses and gratifications model, theories of one-way and multi-way communication, theories of social media and relationship marketing.Conclusion: By making use of social media the company releases some of its control to the customers as the latter can express their opinions freely in this type of media. One of the advantages of social media is that the platform favors dialogue and feedback. Social media can be used for traditional one-way communication, but works best as a supplement to the regular marketing activities, allowing the activities on social media platforms to focus on branding and building long-term customer relationships.
Mobil kommunikation och högre tillgänglighet vid längre elavbrott : Exemplet stormen Dagmar och 4G-kommunikation inom smarta elnät
To be able to secure a safe and reliable power supply is becoming increasingly important since society depends on services and functions that need continuous power supply. The delivery rate in Swedish power supply is 99.98 % which insists on a high availability. During the past decade several storms has passed Sweden which resulted in large amount of tree felling leading to extended power outages. During these storms many socially critical activities, such as electric utility company Fortum, experienced disruption in mobile communication which affected the crisis management. This paper has investigated Swedish mobile operators? crisis management at Hi3G, Tele2 and TeliaSonera with a case study of the storm Dagmar that hit Sweden during December in 2011.
Investment in project preventing deforestation of the Brazilian Amazonas
The aim of this thesis is to create an understanding of the incentives for forest companies to invest in reducing carbon dioxide emissions from deforestation and forest degradation, which is termed REDD. The Brazilian Amazonas was chosen as the base for the investment case. Brazil has the largest area of rainforest in the world, and also the biggest problem with deforestation. The Amazon region of Brazil comprises rainforest which is largely intact and unexploited. Accordingly, there is significant potential scope for prospective investments in a REDD-project, and so have a noteworthy impact in preventing deforestation.The research approach used the United Nation?s Clean Development Mechanism concept was used as a framework for ascertaining the investment costs in potential REDD-projects.

Katalogisering av ljudupptagningar: En komparativ studie av Statens ljud- och Bildarkiv och Sveriges Radios grammofonarkiv
The aim of this thesis is to explore and outline the cataloguing of sound recordings at two main Swedish audiovisual archives, The National Archive of Recorded Sound and Moving Images Statens ljud- och bildarkiv, SLBA and The Grammophone Record Archive of the Swedish Radio Sveriges Radios grammofonarkiv and its data base GAMBA. As non-book, non-printed, material in many ways differs from printed material, the institutions that deal with this kind of material have often developed their own rules for the cataloguing of it. The general codes for cataloguing, AACR2 and KRS, are insufficiently suited for audiovisual material. That is the reason why the IASA Cataloguing Rules, presented in this thesis, have been created. After the presentation of the IASA rules the problems of accounting for important sections of the catalogue record are discussed such as title, statement of respeonsbility, performers, physical description and notes.
